Arcon was developed using both Delphi and C++, and the current version is still in Delphi 2 and C++, and so is not a .Net product.
All versions based on the Arcon engine are cut down version of the professional version which is only sold in the German market.

Although it does run on Windows 7, it is not fully Windows 7 compliant.
